Two unconventional things I do to improve my iPhone's battery health (which follow this article's findings): 1) Don't use a case - Otherwise, you are literally wrapping your phone in a rubber insulator 24/7, increasing its overall temperature. 2) Don't charge at night - Turn off your phone at night. Instead, charge it during the day when you're at your desk. This reduces the number of cycles over years (because your phone is continually draining/recharging all night even when you aren't using it)

iOS will not fully charge your battery during the night - it will top off the battery just before you usually take it off the charger in the morning (it learns your usual schedule + it probably also makes sure the battery is ready based on your alarm settings).

This feature doesn’t help. The problem is that the phone is still using energy during the night, draining the battery by, for example 8-10%. Over several nights, this adds up to 1 cycle.

The fact that the OS waits to top up the battery just hides how much energy it used on background activity and notifications during the night.

In the US there's also an iOS charging option that considers the local grids carbon intensity.

Can’t use the battery if the device is shattered. No case is not an option for my clumsy self.

Turning off my phone at night is not an option. I want to be contactable in case of emergencies.

Are you sure of this? What are you basing this on?

When the phone is on, it’s powered by the battery.
